Description

A REMOTE OBSERVING SYSTEM FOR PRACTICE OF ANTIAIRCRAFT GUN USING TEMPERATURE SHEET}

The present invention relates to a firing training monitoring system, and more particularly, a thermal sensor capable of remotely flying an anti-aircraft target using an unmanned aerial vehicle and monitoring and evaluating an anti-aircraft training shell penetrating through the anti-aircraft target at a spaced position. It relates to a target remote monitoring system used.

In modern warfare, speed and military technology dominate the war, and control of the right to gain control is important because it gives a significant advantage in the war. Securing the right to do so is possible when the radar device involved in terrain detection and attack target tracking, missile weapons that are fired and defeated after the target is set, and armed aircraft for air and ground attacks are appropriately controlled and used. You lose.

For example, a number of anti-aircraft weapons aimed at attacking the air, including aircraft, are installed in major military areas and buildings requiring protection during an air attack. These anti-aircraft aircrafts use the radar tracking to calculate the coordinates of the target when an actual bandit or missile appears, and then launch an aerial attack toward the target. However, in the anti-aircraft drill to prepare for most air attacks, it proceeds with a one-way drill in which a virtual bandit emerges and aims at the shooting position toward the virtual bandit.

In such a case, when a live shot is fired through the air reconnaissance aircraft, an explosion sound or smoke is generated accordingly, and smoke is generated even when the anti-aircraft is hit by the bandit's attack. There is a problem that is quite difficult. In order to solve this problem, a remotely controlled model aircraft has been used to navigate a predicted approach path while conducting a laser ground attack, and a large-scale aircraft has a laser launching device and an explosion sound and smoke generating device to create the same environment. By attaching the device, a device that can experience the same electric field effect as in practice has been developed.

For example, as shown in FIG. 1, the anti-aircraft attacks 10 and 11, which are applied to the air attack against the air attack, and the laser firing apparatus mounted on the anti-aircraft machines 10 and 11 to emit a laser beam toward the attack target ( 20), an image sensor unit (not shown) for receiving a laser beam hit by the laser beam against the target of attack by the laser launch device 20, and while sailing the surrounding air of the anti-aircraft machines 10 and 11; Model aircraft 40 having an attack and defense capability by the laser beam, and aircraft control device 50 for remotely controlling the model aircraft 40. The anti-aircraft 10, 11 is a portable missile launcher (11), Balkan, Oricon, etc. equipped with a laser launching device 20 at the end of the barrel, the laser launching device 20 is a laser beam by the bombardment instructions A laser beam emitting unit (not shown) which generates and outputs a laser beam detection unit (not shown) that detects whether the laser beam is emitted by the laser beam emitting unit and generates and outputs a laser beam detection signal according to the detection result. It consists of.

When the image sensor unit receives and photographs the laser beam reflected by the model aircraft 40 and returns to the computer C1, the reflection point of the laser beam is displayed on the computer C1. Determining how far off the center the hit position is confirmed.

However, as described above, the conventional large-aircraft training system has a problem that many trainees have little chance to participate in such training because a large number of systems, such as a computer for receiving and photographing a laser beam, must be built, including a laser launching device. . In addition, while the anti-aircraft training actually used uses a bullet, conventionally, since the anti-aircraft training should be performed by using a laser, there is a problem that may decrease the sense of actuality.

The present invention was created to solve such a problem, and an object of the present invention is to maintain the same training method as the anti-aircraft gun used in practice, while using a thermal sensor that can monitor the results of the training in real time remote target In providing a surveillance system.

Another object of the present invention is to provide a remote target monitoring system using a recessive sensor that can be provided as a generalized training equipment by simplifying the equipment for anti-aircraft training, such as combat.

Target remote monitoring system using a thermal sensor in accordance with an aspect of the present invention for achieving the above object, in the system for anti-aircraft gun training, radio flying by a training tube, a model for transmitting a target detection signal as a radio signal airplane; A target plate for inducing a change in voltage or current and assuming it as the target detection signal when fastened to a predetermined position of the model airplane and penetrated by a training antiaircraft shell; And a target remote monitoring unit configured to receive the radio signal transmitted from the model airplane at a position spaced a predetermined distance apart, and determine whether to hit the AA gun based on the received target detection signal.

Specifically, the model airplane includes a wireless flight module for performing a flight based on a radio signal transmitted from a long distance; A constant current supply unit for supplying a rated voltage and current to the target plate; A power supply unit for applying driving power to the constant current supply unit and the wireless flight module; A current change detector for detecting a change in current when the power supplied by the constant current supply unit passes through the target plate; An AD converter for converting the analog signal detected by the current change detector into a digital signal; And an RF transmitter for transmitting the output data of the AD converter to the target remote monitoring unit.

The present invention is a system for monitoring anti-aircraft training, not only easy to implement the system, but also low cost of mass production has the effect that can be quickly applied to all flight training. In addition, the present invention has the effect that can be trained similar to the actual anti-air fire shooting to increase the efficiency of the shooting training.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a block diagram showing a system for air defense training monitoring according to the present invention. As shown, when the aircraft is flying by air, the model plane 201 for transmitting the target detection signal as a radio signal, and is fastened to a predetermined position of the model plane 201 and penetrated by the training antiaircraft shell Receiving a target signal 203 and a radio signal transmitted from the model airplane 201 at a predetermined distance from the target plate 203 for inducing a change in voltage or current and assuming it as the target detection signal. Based on the target remote monitoring unit for determining whether or not to hit the anti-aircraft shooting is composed of 207.

The model airplane 201 is capable of simulating flight by a training tube through an RF module, and also supplies a predetermined value of current and voltage to the target plate 203 and changes the current of the target plate 203. Detect it. The current change is converted into a digitized signal and provided to the target remote monitoring unit 207 through a predetermined protocol. Description of the adjuster for wirelessly adjusting the model airplane 201 is omitted. Here, the model airplane 201 will be described in detail.

3 is a view showing the main configuration of the model airplane 201. As shown, a wireless flight module 301 for controlling flight of the model airplane 201 based on a radio signal transmitted from a long distance, and a constant current supply unit for supplying a rated voltage and current to the target plate 203. 305, the power supply unit 303 for applying driving power to the constant current supply unit 305 and the wireless flight module 301, and the power supplied by the constant current supply unit 305 to the target plate 203. When passing through, the current change detection unit 307 for detecting a change in current, the AD converter 309 for converting the analog signal detected by the current change detection unit 307 into a digital signal, and the AD RF output unit 311 for RF transmission of the output data of the converter 309 to the target remote monitoring unit 207.

Here, when the anti-aircraft shell is hit by the target plate 203, the change in the current supplied to the target plate 203 will be described. First, Figure 4 is a block diagram for explaining the structure of the target plate 203 according to the present invention. As shown, power lines for supplying DC power to both ends of the target plate 203 are formed, and a plurality of resistors R are connected in parallel between the respective power lines. The resistor has a line shape, it is preferable that the spacing of each resistor (R) is slightly larger than the diameter size of the anti-air shell. This is to ensure that when the anti-aircraft shell hits the target plate 203, only one resistor R is disconnected. Of course, even if the spacing of the resistor (R) is set to a multiple of 1 / N (N = integer) of the diameter of the air hole shell will not depart from the gist of the present invention.

As described above, when the plurality of resistors R are hit by the shells of the anti-aircraft gun 205, any one or N resistors R are disconnected, and this disconnection phenomenon is the amount of current consumed supplied to the power line. This decreases. The model airplane 201 detects a change in current caused by the power failure phenomenon.

Hereinafter, the operation of the present invention will be described.

The training pipe includes the model airplane 201 and controls the flight of the target plate 203 connected to the model airplane 201. This controls the flight of the model airplane through the wireless flight module 301. When the model airplane 201 is flight-controlled by the radio controller of the training tube, the target plate 203 is flying along the radio airplane 201, and the anti-aircraft gun 205 uses the training shell and the target plate ( 203). The target plate 203 may be set to a width of 3.5m, a height of 0.9m.

The target plate 203 is supplied with power to the power line of the target plate through the power supply unit 303 and the constant current supply unit 305 mounted to the model airplane 201. The power supply consumes a fixed amount of current by the plurality of resistors R constituting the target plate 203 at a rated voltage. For example, when m resistors R are connected in parallel, the total resistance becomes R / m k. At this time, when any one of the plurality of resistors (R) (R) is disconnected by the anti-air shell, the amount of current supplied to the target plate 203 is R / (m-1)).

As described above, when the plurality of resistors R provided as the target plate 203 are hit by the anti-aircraft shell, any one of the resistors R is disconnected and the amount of current supplied to the target plate 203 is variable. do. The variable current amount may vary depending on the number of resistors R, but the current consumption of about 0.3 A is reduced based on the practical density of the resistors R. FIG.

That is, the current change detection unit 307 monitors the amount of current supplied to the target plate 203, and detects the current change caused by the anti-aircraft shell as an analog signal. In addition, the current change detector 307 provides an analog signal according to the current change to the AD converter 309, and the AD converter 309 performs a digitized signal change. Thereafter, the RF transmitter 311 modulates the digital signal supplied through the AD converter 309 into a signal of a predetermined frequency band and transmits the digital signal to the target remote monitoring unit 207.

The target remote monitoring unit 207 receives a change in resistance, that is, a current change amount data, for the target plate 203 hit by the anti-aircraft shell. Then, it is determined whether or not a hit against the shot of the anti-aircraft gun 205 based on the current change data. The target remote monitoring unit 207 may be a computer system capable of interworking on the web, instead of merely receiving current change amount data. For example, the shooting score of the anti-aircraft gun 205 may be viewed online at a location such as a training control station spaced from several Km to several tens of Km, and the shooting information and the carriage information may be provided to the control station. There will be.

On the other hand, the target plate 203 in the present invention has a sheeted structure, but, of course, can be transformed into a cylindrical target plate, a spherical target plate, a plane target plate, and the like, as necessary. In addition, although the target plate 203 of the present invention has been described as a resistor R having a line shape, a resistor sheet having a surface shape in which the size of the resistance varies depending on the surface area may be used. When the shell of the anti-aircraft gun hits the resistor sheet, the area of the target plate is variable, and the resistance value is varied by the variable area. The current change detector 307 detects a change amount of current based on the change in resistance.

On the other hand, the current change detection unit 307 has been described for detecting the current change for ease of description, it will be able to detect the voltage change, the resistance change. Such a function may vary according to the connection structure of the resistor R constituting the target plate 203, and may apply a function necessary according to a system implementation.

The anti-aircraft fire training monitoring system according to the present invention is a system applicable to military training, it is possible to perform the training, such as practice and the cost of implementing the system itself will be extremely high industrial availability.
